GDP Outpaces Energy Consumption

Residential and commercial sectors will likely have increased energy efficiency offsets growth in energy demand in residential and commercial sectors. Energy consumption grows about 0.4% per year on average, while GDP is expected to average 2.0% annual growth to 2050 in the reference case, showing a decoupling between economic expansion and energy use. Lighting displays the largest drop in both sectors due to the increasing penetration of LEDs.

On the residential side, all types of appliances are expected to become more efficient, water heating shows a sizable decrease due to heat pumps, among other reasons, while cooling actually has an increase resulting from a continued population shift to warmer parts of the US, lower heating demand, and increase cooling demand. However, increased adoption of electronic devices contributes to growth in residential use of electricity.

Electricity used for commercial HVAC equipment is likely to drop by more than one-third from 2017 to 2050 in the reference case because of increases in energy efficiency and a continued population shift toward warmer parts of the country in the South and West. Although the US has no federally-mandated commercial building energy code, state and local-level building codes reduce energy used for heating and cooling.

Use of Purchased Electricity per Household (Reference Case) – Thousand Kilowatt-Hour per Household

Light duty vehicle fuel economy will likely improve as sales of more fuel-efficient cars grow and as electrified powertrains gain market share, but gasoline vehicles remain the dominant vehicle type through 2050 in the reference case. Combined sales of new EVs, plug-in hybrid EVs, and hybrid vehicles are likely grow in market share from 4% in 2017 to 19% in 2050.

During the press conference where these results were reported, there were audience questions that challenged some of the AEO’s assumptions about renewable energy and energy efficiency growth. Such concerns have also been raised after reading the report as well. The AEO does include a number of high and low cases to try to represent the range of potential outcomes. It is important to consider the AEO as a point of reference, but not take it as gospel. As a professional market research analyst, my goal is for my analysis and forecasts to reflect the general trends in the industry and spark intelligent debate.
